Momwe mungasiyanitsire lingaliro la kusakhala kawopsedwe ndi chitetezo cha chilengedwe cha payipi yapulasitiki ya PVC

Makasitomala ambiri sali omveka bwino za malingaliro osakhala kawopsedwe komanso kuteteza chilengedwe kwa mapaipi apulasitiki a PVC, ndipo amaganiza kuti zopanda poizoni ndizosawononga chilengedwe.Ndipotu sizili choncho.Kuti timvetse mozama mfundo ziwirizi, choyamba tiyenera kusiyanitsa zipangizo ndi ntchito za mapaipi.
Kumayambiriro kwa PVC pulasitiki payipi ndi kutumikira anthu ndi ntchito pa moyo wa anthu tsiku ndi tsiku, koma ndi malire kugwetsa pansi, maluwa, minda, makina Chalk, m'chimake, etc. Pachiyambi, ogwira ntchito yomanga malo ngakhale Ntchito madzi operekera.Kuchokera kuzinthu izi, omwe amatha kuyanjana ndi anthu kwa nthawi yayitali ayenera kuweruzidwa kuti ndi opanda poizoni kapena osasamala, koma izi ndizochepa pazopangira zoyambirira.
Lingaliro la chitetezo cha chilengedwe ndi lotakata, ingodinani pa Baidu, pano kuti mulankhule za chitetezo cha chilengedwe cha ma hoses apulasitiki a PVC, zomwe zikutanthauza kuti zinthu zomwe zimawonongeka pambuyo pa kuwonongeka kwa ma hoses a PVC sizidzawononga thupi la munthu.PVC ndi polyethylene, yomwe ndi ufa wa utomoni.Zigawo zomwe zimapanga zinthu zovulaza mu payipi zimachokera ku zinthu zina zomwe zimapanga payipi, butyl ester, chlorinated paraffin, (kapena octyl ester, p-benzene, TOTM).Ma hoses wamba nthawi zambiri amapangidwa ndi PVC, butyl ester, klorini Amapangidwa ndi sera ya paraffin ndi zina zowonjezera.Butyl ester ndi parafini sizingawonjezeke kwambiri benzene kutentha kukakhala kotsika kuposa 45 digiri Celsius, kotero ndizotetezeka komanso zopanda poizoni.
Kutetezedwa kwa chilengedwe kumatanthauza kuti mapaipi a PVC omwe adutsa kuyang'anira mabungwe ovomerezeka popanda phthalate mpweya angagwiritsidwe ntchito pa mapaipi amadzi akumwa ndipo amaonedwa kuti ndi okonda zachilengedwe.Chofunikirachi ndi chokhwima, ndipo zida zopangira zachilengedwe zokha zimagwiritsidwa ntchito.
Choncho, posankha payipi, yesetsani kugwiritsa ntchito zopanda poizoni kapena zachilengedwe kuti mugwiritse ntchito pakhomo.Mtengo umangokhala wovuta panthawi yolipira, ndipo pogwiritsira ntchito mankhwalawa, pali chisangalalo chomwe chimatsatiridwa, ndipo kugwiritsa ntchito chubu kumakhala kopanda nkhawa.
